Geo4�fcal7� <br /> Daal Phase Extraction Pilot Test Report <br /> Project No. 723.2 Page 13 <br /> November 5,2004 <br /> the regular gu ar hydropunch type soil/groundwater samples be attempted using the CPT <br /> rig. The depths of these attempts should not exceed 80 feet bgs <br /> the contamination deeper through clay layers to avoid transortin <br /> identified p g <br /> i Contamination has been identified below this depth on site but GTI bel eseit isa <br /> drilling artifact. . <br /> 3. A full scale Corrective Action Plan (CAP) should be deferred until after the off site <br /> p plume definition has occurred. Once this task is accomplished a full scale CAP can 1 <br /> be developed in accordance with -USTCFP requirements for three <br /> remedial <br /> .alternatives. <br /> .7.0 LMTATIONS <br /> This report was prepared in accordance with theenerall accepted <br /> g y p standard of care and <br /> practice in effect at the time Services were rendered. It should be recognized that definition <br /> and evaluation of environmental conditions is an inexact science and that the state or practice <br /> of environmental geology/hydrology is changing and evolving and that standards existing at <br /> the present time may change as knowledge increases and the state of the practice continues to <br /> improve. Further, that differing subsurface soil characteristics can be experienced within a <br /> small distance and therefore cannot be known in an absolute sense. All conclusions and <br /> recommendations are based on the available data and information. <br /> The tasks proposed and completed during this project were reviewed and approved by the <br /> f local regulatory agency for compliance with the law.
